Randomized Controlled Trial
[Back school for patients with non-specific chronic low-back pain: benefits from the association of an exercise program with patient's education].
has been used as a way of preventing and treating back pain since 1969, but reports in the literature on its effectiveness remain controversial. The purpose of this trial was to evaluate efficacy of a back school program for non- -specific chronic low-back pain. ⋯ The Back School program proposed in this study seems to be effective for non-specific chronic low back pain. -
The aim of this study was to verify the discriminative power of the most widely used pain assessment instruments. ⋯ VAS presented the higher sensibility, specificity and AUC, showing the greatest discriminative power among the instruments. However, these values are considerably similar to those of Dolorimetry.

Ankylosing spondylitis patients are reported to be at greater risk for vertebral fractures and spinal cord injury. We describe the case of a 72-year-old male with a long history of ankylosing spondylitis who sustained a vertebral fracture after minor trauma. The fracture was initially missed on conventional radiographs but was later diagnosed by magnetic resonance imaging after the development of new neurological symptoms. With this case report the authors outline the factors that increase the incidence of vertebral fractures and spinal cord injury in ankylosing spondylitis patients and discuss prevention strategies to avoid this devastating complication of the disease.

Review Case Reports
[Hemophagocytic Syndrome: a clinical presentation of systemic lupus erythematosus].
Hemophagocytic Syndrome is a clinical condition characterized by the activation of either macrophages or histiocytes with a prominent hemophagocytosis feature in the bone marrow and other reticuloendothelial systems. It leads to the phagocytosis of erythrocytes, leukocytes, platelets, and their precursors. The presence of hemophagocytosis can be associated to infections, malignancies, autoimmune diseases, drugs and a variety of other medical conditions. ⋯ There are only few cases reported in the literature. In this article, we briefly reviewed what is currently known about this syndrome. However, much is still needed in order to better understand its causes, all the immunopathogenic mechanisms, as well as its clinical aspects.

Fibrous Dysplasia FD of bone is a rare non-inheritable congenital disease characterized by a focal proliferation of fibrous tissue in the bone marrow leading to osteolytic lesions deformities and fractures. FD can be presented in a monostotic or polyostotic form this last one is usually more severe. ⋯ We describe the case of a male patient with long evolution form of polyostotic fibrous dysplasia of bone with delayed clinical presentation. It is also highlighted the importance of an activity and involvement form evaluation as well as possible endocrine abnormalities associated in order to establish the correct treatment and prognosis.
